The purpose ofthis invention is to provide an improved means for heating the cab of a motor vehicle by means of a circulatory sys-- tem which is primarily provided for cooling It consists in the elements and features of construction shown and described, asindicated in the claim.

In thedrawings: I

iilgure 1 is a diagrammatic view showing 10 the several parts of the system which constiof the arrow, 1, on Figure 3, being an end.

elevation of the pump. with the inlet closure plate removed.

Figure 5 is a vertical section through a 25 three'way valve which isinterposed in the discharge pipe leadingfroin the radiator to the heater at the junction with'said pipe of.

a branch leading to the pump intake, axial with respect to saidpipeandtrans-axial with respect to the valve, showing the valve positioned for including the heaterin the circuit I with the radiator pump and engine jacket.

Figure 6 is a View similar to Figure 5 showing the valve positioned for cutting oil? flow to the heater and opening communication directly with the pump intake. v

.Figure 7 is a detail's'ection at the line, 77, on Figure 6. 5

Figure 8 is an elevation of a member of a 40 three-way valve device above mentioned.

In the structure shownin the drawings, theenginejacket, A, is shown connected directly with the discharge pump,'B, and con nected with the top of the radiator, C, by a pipe, 1. A discharge pipe, 2, leading from the bottom of the radiator, connects the lat-,

v ter with the intake D of the heater located in the cab, andfrom the heater,'the pipe, 8, leads as seen at f, to the intake of the um as seen at Z2 A three-wa valve cas- Figure 4 is a view looking in the direction ingyF, is interposed inthe pipe line, 2,.b'e tween the radiator discharge'and the heater intake, the third connection otsaid'caslng being with the pipe line, 3, as seen at 7, leadmg to thepump intake.

The pump is of thecentrifugal type having its intakea t" the center of i-ts casing, and having tangential discharge at the periphery as seen at 6, into the enginejacket through thefport, a; said pump casing being mounted against the 1 engine acket by -means of the flange, 9,

around the discharge port, whichregisters with the port, a, leadinginto the jacket cavQ ity. The flange, 9, is a part of a bracket ex: tension, 10, of the pump casing, said bracket extension having a journal bearing,11,"for the shaft, 8, of the pump rotor, 7, which extends out of the, pump casing through a journal bearing, 12, provided with a'stufiing look, 13. ISaid bracket extension, 10,1ias set through ita screw, 14, which is adapted to 'be set against the outer wall of the engine" jacket, springing the bracket arm, 10, in slightly in order to align the ournal bearings, 11 and 12. The bracket, 10,"-is held to,-'. .ward, and the screw, M, against the engine body by thepump driving belt, '15, which passes about the J pulley, 16, on the pump rotor shaft, 8. j

It will be understood that atone position 01 the three-wav valve F in the casin F u 3 V ,7 V 3 7 shown in Figure 5, said valve affords communication directly from the discharge of the radiator to the intake of the heater, through the entire length of the pipe line,

2, so that there is a single circuit for the water, in which are contained both the radiator and the heater; and that at another position of said valve, F shown in FigureG, said valve cuts cit communication through the pipe line, 2, between the radiator and the ll&i361,'LDCl opens communication from the radiator tothe pump intake; so that there is still only a single circuit, but this'circult does not include the heater, but only-the radiatorin connection withthe pump and engine jacket. It will also be seen that the valve, F maybe set at an intermediate position at which it will only partly close the communication through the pipe line,

2, to the heater, and only partly open com nunication into the pipe, 3, so that the hot f -water withdrawnfrom the discharge of the radiator will partly pass said valve toward the heater, and through the heater and thence back through the pipe, 8, to the pump intake, and another part of the water will I pass directly from'the valve to the pipe, 3, *and to the pump intake. The valve, Fflhas its stem provided with a lever handle, 18, for operating it, and thisflhandle may, if desired, be provided with a connection extending intothe cabso that the circulation may be controlled at the will of the occupant.

We claim 7 7 A fitting for'the purpose indicated com-' prising two parallel water passages each 7 open at both ends with a transverse water connection between them intermediate their ends one of said passages having a cylindrical chamber disposed: substantially at the point of intersection between the passage and the transverse connection, the axis or" said chamber being transverse to the axis 7 of the passage and the connection, whereby the cylindrical wall of said chamber comprises three. ports, together with a valve member in the form of a hollow cylinder having a portion of its cylindrical wall cut away, the remaining portion being sufiicient in extent to cover only one of saidthree' 'ports'at a time, and means foryturning said valve member about the axis of the valve chamber, one'of said parallel passages terminating in a connection flange, for attach mentto a pump, the other end of said passage and the corresponding end ofthe other parallel passage being formed for connec tion with flexible tubingto communicate 40 'with a heater coil or the like.

In testimony whereof, We have hereunto setour hands at Chicago, Illinois, this 26th- 7 day of October, 1922. r V i HENRY KOCOURE K.
